What it is

The Ideal Washer Pack Solar is a set of sealing washers supplied by Ideal for use on its solar thermal equipment. The washers sit at the union joints on solar collectors and thermal stores, where they compress to form a watertight seal and stop fluid escaping from the connection. The pack is listed under Ideal part number 174873 and is also referenced under the number 1780302.

Signs this part needs replacing

  • Water weeping or dripping from a collector or thermal store connection
  • Washers that have hardened, flattened or cracked after repeated heat cycling
  • Scale, corrosion or staining around a union joint
  • A joint that continues to leak after being tightened
  • Gradual loss of pressure in the solar circuit with no obvious pipe damage

Before you order

  • Check your appliance against the compatibility list, as the pack covers several Solar Pack collector configurations as well as the Solar Thermstore 180.
  • Note the alternative number 1780302 when comparing listings or old paperwork.
  • This is not a gas part.
  • If the joint is being resealed as part of wider work, confirm whether a gasket or o-ring from the same range is also needed.
